VR-4SR MkIIIa up and singing

They are here and they are a revelation.

Much improved clarity in the midrange and sounding eerily like big Unifield 3s. I suspect that Albert has moved the crossover frequency up and over 4kHz on this iteration to achieve the effect. It also appears that the AAC midrange driver is less padded than the previous models giving improvements in "jump". The new non-liquid cooled tweeters are much quicker of the starting block enhancing transients while staying smooth but less laid back by the old Vifa ring radiator. I can see how these may have given Albert fits in the revised passive servo control circuit. The quicker the driver the more difficult to map and compensate.

What stood out to me is the low level resolution of timbres. They do come close to VR-5 SEs albeit I should add that the VR-5s are more delicate and pure up top and the Audax units have an edge in off axis response over the AAC units. Bass on the 5s are likewise quicker and more tuneful with as little as 50 watts of tube power while the Aluminum woofers the SRs go lower but need in my opinion at least 150 high current watts with out which the SRs are more midrangey and suffer from a mild but noticeable midbass suckout with not enough juice.

The SRs are very revealing and has rock solid imaging. So revealing that differentiating instrument sections in dense classical works is a breeze. Perfect for Peter and the Wolf session with your kids.

Fit and finish of the piano blacks is top notch and mirror like. I particularly like how the plinths are finished in piano lacquer as well. The back panels which now eliminate the datalink option is clean and classy and the binding posts have also been improved over the SR Mk1s.

All in all it is a stunning accomplishment in its price class. Matched with a quality high current amp, the SR MKIIIs make for a compelling backbone for mixed audio and HT system. They worked quite beautifully with the Lamm ML1.1 90wpc tube monoblocks but showed their true potential with the less expensive Lamm M2.2 220wpc hybrids. The VR-5s did well with either.

Kudos to VSA for giving two fantastic options in the Unifield 3 and the SR MkIII. Choosing between the two to my ears would depend purely on the size of the intended listening space as they both do so much right and do so little harm by offering practically no distractions from simply getting into the music.

Thanks for sharing Jack!

I recently bought back my old pair VR4Jr. ,and I'm having amazing musical results biamping with some class D Hypex UcD 400(sounds very similar to my Channel Island Audio D200 ,think they use the same class D module) on the bass,and an absolute fantastic 6L6 tube integrated on top,Consonance M99!  :)
I've never managed to get biamping sounding coherent enough for my taste before,and I didn't manage this good result even with the DB99. This is just the most fun I've had with all recorded music on a hifi set-up!
Now I regret I sold my VR5Anniversaries :duh:  ,but this amazing result really ticked me to maybe consider VR4SRmkIII or the VR5Annies again.

How about some pictures? One of the best setups I've heard were VS VR-4SR with VAC amplification.

Sorry for the blotchy pics. I just used a point and shoot for these quick shots  :oops:

Nice Setup Jack,

You have a lot of CeeDee's to play.

Enjoy the music.

Hey there Jack,

Those are the MKIIIs with Al bass cones correct?  Is this your system?  A second pair of LAMMs??  Woah.  I've noticed that you don't have these nor your VR9s toed in at all.  Have you determined that straight ahead is better?  for bass reponse? soundstage? imaging?  Great looking setup but it's not fair for one guy to possess this many great toys.... :drool:

Yes CeeDee! I will play as many as I can before I have to deliver the pre and the amps  :thumb:

The speakers are mine Gavin (for my upcoming HT along with a VisiUN to be powered with a BAT VK-6200), this pre is sold and so is are these pair of M2.2s. The guy who owns the preamp (who also bought an identical pair of MkIIIs and a pair of Lamm M1.2 References) is still waiting for his cables and the M2.2s are waiting for their owner to finish his music only multichannel listening room where they'll be used with VR-9s...get this....for REAR duty. :scratch:

I'm having a blast with this system while I can though by coincidence it is made up of VSA's and Lamm's least expensive products. It's kinda twisted really  :lol: :lol: :lol: Together, they're already way more than any discerning music lover needs. This is trickle down technology at it's best. I highly commend both Albert and Vladimir for always making the best products at any given price point unlike others that intentionally dumb down models to avoid cannibalizing sales of the next one up the ladder. :D

Toe-in? It's a bit of an optical illusion. The speakers are 9 feet apart and they are toed in about 3 inches each. The 9s are slightly toed in as well. Toe in is a habit acquired by need over the years by most of us because most of us started out with speakers using first order crossovers that have off axis responses that weren't very good. Years ago when I got my first pair of 4th order speakers (Revel F30) I found less toe in was needed to achieve both focus and solid center fill. Same thing when I got my first VRs the VR-4 HSE Gen.IIIs. All VRs will give solid center fill pointing straight ahead up to 9 feet apart. At this distance toe in is really just for achieving the subjectively desired focus which falls anywhere between live which is huge and diffused (toed out or straight ahead) and hyper focused (straight at ya). In a lesser way toe in also affects stage height. Again at this distance adding toe in will drop the height slightly. If I wanted a bit more height back I'd move the speakers a few inches forward. Just enough to raise the stage height but not enough to dip the bass.

Fellow dealers call me the human raytracer because we're always the fastest to set up and tune at shows. They love it because on move-in day that means Keith and I always have time to help them out with their rooms too. Now you see why we get such sweet deals on stuff we don't carry  :eyebrows: It's a skill developed from when Keith and I were DJing and setting up actively XO's PA rigs when we were in school. We were forced to optimize systems (our own stacks or rented ones for the really big gigs) for anything from cramped living rooms at house parties to grand ballrooms for debutantes' coming out parties and weddings. The goal was always to optimize vocals on the recordings while allowing the guests dancing to be able to still talk (hence providing ourselves and other blokes better scoring opportunities  :roll: ) while again giving punch, grunt and drive to get them freaky  :lol: :lol: :lol:  In hindsight it really is no different from tuning a home system except that you no longer have control over gain on the XO and no longer have the parametric EQs on hand. These are replaced with elbow grease and imagination. The goal remains to lock in the room/loudspeaker interface so the tonal balance is even and coverage is as wide as possible without sacrificing intimacy. See what I mean about scoring opportunities? I knew my wild oats would amount to at least SOME good someday!

I think Albert never imagined the VR9 will be used for rear duty...

Hey there Dimfer! Thanks again for the AVM treated Le Fille XRCD you gave me!!!! I have been using it as a reference from day one. The other discs I'm being selfish with  :eyebrows: :eyebrows: :eyebrows:

Yes he is Gavin. Albert did a 4ch multichannel demo at CES 06 I believe with Herve's DarTZeel amps and Meitner switchman and DAC6 gear with 4 VR-9s. It won best multichannel sound in TAS that year. That someone will actually do it is something else altogether. Heck, I STILL can't believe it! It is going to be one heck of a backbreaking installation job. Just leveling the 9 levels of CMS QXKs alone will probably take a day.

Very nice setup! Congrats with new front speakers, they look stunning!

The new midrange it self gives about 50% more information then the presuccessor. :)

I'm inclined to agree A. It is definitely more resolving and more dynamic to boot. In a month's time the matching VisiUN Mk2 Center comes out of the box to join them. With what I experienced with the Mk.1s and SR Mk.2s I'm going to be in for a real treat. The VisiUN Mk.2 is essentially a Jr Mk3 on its side using the same tweeter a smaller AAC midrange and twin 6.5" SEAS Aluminum woofers. You should get one too to complete your array Ambience.  :eyebrows:

Oh boy, you don't know he who is called Emperor. The guy is a perfectionist bordering on OC. He lurks here BTW so I'm definitely screwed  :lol: :lol: :lol: Just kidding Jim, I know you're reading this  :thumb:

Leveling a four posted rack that weighs about two hundred pounds is tough enough. He has expressed his wishes that all three racks be lined up exactly AND with exactly the same height to boot! That's a brier patch I'm not throwing any friend to bro!
